Optional parameters to webservice method over FORM-GET

Question

Hi.
I'm developing a proof of concept webservice using Workshop and my test method looks something like this:
     * @common:operation
     * @jws:protocol soap-style="rpc" http-xml="false"
        form-post="true" http-soap="true"
    public void foobar(
        String param1, String param2, String param3)
    }The schema elements I map to the parameters specifies that they are optional.
There are no problems when using this as a webservice - I'm able to specify these optional parameters (or not). When I invoke this using FORM-GET, it seems that these parameters are all required (although I can specify an empty value).
E.g. The following works fine:
http://localhost:7001/TestWebService/Test.jws?param1=abc&param2=def&param3=ghi
The following works fine and calls my code with param1 being an empty string:
http://localhost:7001/TestWebService/Test.jws?param1=&param2=def&param3=ghi
The following returns an error:
http://localhost:7001/TestWebService/Test.jws?param2=def&param3=ghi
The error is: "Unable to transform query arguments to Java arguments Parameter 'param1' - No value found"
Can anyone advise on how to not require the presence of optional parameters using FORM-GET?
Regards,
Michael.

Hi,
thanks for the quick turn-around. Jdev version that i am using is Studio Edition Version 11.1.1.6.0. And i am using SOAP. Isnt there a way without using a backing bean? I am planning to use it as a portlet. Would'nt creating a backing bean cause a problem in that case?? Also i am confused here . The method that i am dragging is GET_ACCOUNTOperation(Object). I tried passing the hashmap . It gave the following exception :
javax.el.MethodNotFoundException: Method not found: GET_ACCOUNTOperation.execute(java.util.HashMap)
